"After using Scott Marx for years (he used to be employed by the company we used for decades before it closed) he started to act weird and did things poorly. Issue in January 2025 was back and forth stating it was 5 different things. Also, we had to pay 364.31 for a control board that he said we needed and then after giving him the check to get the board all of a sudden it was not needed. He was to return the board and get us a refund. It ended up we had to call the police to get our money back!!! Lots of games and non-returned calls and so forth. Then we learned from the PA web site. that he failed to renew is license in November 2024!!! I would say, stay away from him. Was good at the beginning, but the past year and more so the past month, very shaky!!!"

The problem with most "pros"? Too many bad habits. It's easy to get swept away in the day to day monotony, even for those that call themselves "pros". When it comes to hiring a heating and cooling technician, nobody wants to deal with being treated like a sale rather than a person, the use of scare tactics instead of education, or someone who just wants to get to job done quickly instead of correctly. All our HVAC pros go through 5 years of HVAC schooling, for a total of 10,000 hours of on-the-job training. And it's not just technical training either; it's training that focuses on you, on making you feel comfortable every step of the way. We will roll out the red carpet for you, both figuratively and literally. Red Carpet Treatment During every visit to a home, we lay out an actual red carpet to prevent any additional mess. But what may be even more important than just protecting your home is making sure you feel like you've received the best in customer service.

As a father of five children, I understand the importance of receiving quality work for a fair price. For 39 years I have been very honest with my customers and would never give them anything less than I would desire for myself or my family. I offer high quality equipment, and, like an artist, I take pride in providing my customers with an impeccable job. So, if you are looking for an excellent contractor with competitive pricing, call my company! Servicing Cranberry Twp., Mars, Gibsonia, Warrendale, Wexford, North Hills, Zelienople and the surrounding areas.

Heating and air conditioning services FAQs

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
